Subject: [PATCH v1 1/1] pinctrl: nuvoton: modify NPCM7xx pin configuration function
Date: Wed, 7 Nov 2018 15:44:34 +0200 [thread overview]
Message-ID: <20181107134434.354795-2-tmaimon77@gmail.com> (raw)
In-Reply-To: <20181107134434.354795-1-tmaimon77@gmail.com>
Modify GPIO direction setting in pin configuration function by using
generic GPIO functions to set the GPIO direction instead of direct
access to the GPIO direction register.
